［摘要］近幾年地下水位上升導致建筑結(jié)構破壞時有發(fā)生。針對上述問題，對抗浮水位的獲取途徑、抗浮設計內(nèi)容和措施等進行了闡述、總結(jié)，并詳細介紹了抗拔樁與抗拔錨桿的布置原則，最后對三個工程實例進行了抗浮設計。得出如下結(jié)論：在進行防水板厚度計算時，不應考慮抗拔錨桿的支點作用；當管廊橫截面寬度超過6m時，建議不要單純采用底板外挑抗浮措施。從經(jīng)濟性上考慮，抗拔樁應盡量選擇樁徑較小的樁。
［關鍵詞］抗浮設計；抗浮水位；抗拔樁；抗拔錨桿；抗浮措施

Abstract:In recent years, the rise of underground water level has leaded to the failure of building structures from time to time. With regard to the above problem, the approach of obtaining anti-floating water level, anti-floating design content and measures were elaborated and summarized, and the arrangement principles of uplift piles and uplift anchors were introduced in detail. At last, anti-floating designs have been made for three engineering projects. The following conclusions are drawn that when calculating the thickness of the waterproof plate, the fulcrum function of uplift anchor should not be considered; when the cross-sectional width of the pipe gallery exceeds 6m, it is recommended not to simply adopt the anti-floating measures by means of overlanging bottom plate. Considering the economy, the pile with smaller diameter should be chosen as far as possible for the uplift pile.
